ggplotgeom_sf for handling sf
objectsWe can use the fill attribute. For example, let’s make the fill dependent on the ratio of perimeter to area, so wigglier/more connected places are hotter colours r
nc %>%
mutate(
wiggliness = PERIMETER / AREA
) %>%
ggplot() +
geom_sf(aes(fill = wiggliness), color = NA)tmaptmap is quite similar to ggplot2 in operation, but just
focused on maps, and having defaults that work well with spatial
data
And to fill polygons based on a value
Plotting with interactive tmap
tmap has an option to create interactive version of the
above (static) maps, using the leaflet package.## tmap mode set to interactive viewing
Note the addition of a standard base map layer.
to switch back between modes
## tmap mode set to plotting
## tmap mode set to plotting
When in view mode (using leaflet), different basemaps
can be selected by specifying a valid selection from
leaflet::providers). Here’s the default example:
## tmap mode set to interactive viewing
data(World, metro)
tm_basemap(leaflet::providers$Stamen.Watercolor) +
# tm_basemap(leaflet::providers$CartoDB) +
tm_shape(metro, bbox = "India") + tm_dots(col = "red", group = "Metropolitan areas") +
tm_tiles(paste0("http://services.arcgisonline.com/arcgis/rest/services/Canvas/",
"World_Light_Gray_Reference/MapServer/tile/{z}/{y}/{x}"), group = "Labels")## old-style crs object detected; please recreate object with a recent sf::st_crs()
## old-style crs object detected; please recreate object with a recent sf::st_crs()
## old-style crs object detected; please recreate object with a recent sf::st_crs()
## old-style crs object detected; please recreate object with a recent sf::st_crs()
## old-style crs object detected; please recreate object with a recent sf::st_crs()
Both the basemap and tiles are rasters (bitmap image files). The difference is that tiles go on top and the basemap is at the bottom. (maps being composed of successive layers, much like ggplots)
